HORATIO G. GILLMOR, OFaWASI I INGTON, DISTRIC'I O F COLUMBIA.

, Specification of Letters Patent. Patented N 11, 1919,

Application filed. April 11, 1918. Serial No. 22 ,es2 I"- ing is a specification, accompanied by drawings.

Thls invention relates to devices commonly known as rail anchors, rail stays or anticreepers and one of its objects is to provide a device which may be attached to or used with a tie plate and which will effectually prevent longitudinal movement of the rail in either direction.

A further object is to provide an improved rail anchor in which the clamping or gripping engagement is with both the base and the head of the rail and is effected through the instrumentality of a spring which is strained when applied to the rail" so as to eXert stress which will absorb vibration and take up looseness due to any cause. In a tie plate attachment for preventing creeping there is ordinarily contact between the attachment and the tie plate over a relatively small surface; and, on account of the wave movement which takes place in rails, there will be some movement of the attachment in relation to the tie plate, which movement will in time result in wear of the softer part. The use of the spring in my invention prevents such wear from resulting in the loosening of the grip of the device upon the rail;

A further object is to provide a rail anchor which, while having the necessary strength will be very light in weight. Weight is an important consideration because of the saving in' manufacturing cost and also in the transportation of the anchors to the point where used.

The invention is illustrated, in one embodiment, in the accompanying drawings in which:

Figure 1 is a side elevation of the device shown as applied to a railroad rail, which is shown in section.

Fig. 2 is an end elevation of the device in its operative position on the rail, showing a portion of one of the ties.

Fig. 3 is a side elevation, showing the rail in section, illustrating the method of apply in the device to the rail.

*ig. l is a perspective view of the spring. Fig. 5 is a plan view of the rail base engaging shoe.

In the drawingssimilar letters apply to the corresponding parts in the several views.

Referring to the drawings, A represents the rail whiclrrests upon a tie plate B, which latter, in turn, rests upon a tie C, to which the rail and the tie plate are secured by spikes or screws D. The rail anchor, illustrated in the drawings as an attachment to the tie plate, consists, in addition to the tie plate B, of two'members E, Fig. 4, and F, Fig. 5. The member E consists preferably of a rectangular bar of steel which is bent to form two legs G and H, the ends of which may be rounded at I to conform to the shape of that portion of the rail head with which this is to engage and at K to facilitate the placing of the spring in position. The member F is a shoe, which engages. the upper surface of the rail base and is provided with a flanged portion L, ex"

tending downwardly along the edge. of the rail base. The middle portion of the member F is constructed with a seat M, which is arranged to receive the leg H of the member E, each side of which are shallow flanges N, which guide the inen'iber E, while being forced into position and hold the leg H in position. The member F has also near the middle of its length and outwardly of the seat M a heavy rib O, at the lower end of which there is provided the projection P, which is arranged to engagethe aperture R in the tie plate B. This aperture It would ordinarily be one of the spiking apertures with which all tie plates are provided. The projection P may have one or more of its faces tapered as at S in Figs. 1 and 3.- The tie plate B may have a longitudinal rib U arranged to engage the edge of the rail base.

To place the device, the tie plate B is placed in position with the rib U engaging the edge of the rail base along the whole length of the tie plate and the shoe F is then placed with the projection P engaging the aperture R in the tie plate B. The fit of the parts may be such that it will then be necessary to drive the projection P into the aperture R until the shoe F is in the position illustrated in Fig. 3. With the shoe F in this position the spring E is placed with the rounded point K of the arm H on gagingthe seat M of the shoe F and the rounded end I of the arm G engaging the rail head. From this position to thefinal to move angularly, the rounded end I mov spring about an axis adjacent the rail head engaging portion of said spring.

8. A device for preventing the creeping of rails, comprising rail gripping elements, one of which is a part engaging the rail base at one side of the rail and held in fixed position in the roadbed and one of which is a two armed resilient element arranged to be forced in between said part and the rail head by rotation about an axis adjacent the rail head.

9. A rail anchor, comprising a holding plate provided with means for engaging one side of the rail base and a fixed portion of the roadbed, a part engaging said holding plate and the rail base and a resilient element constructed to be forced in between said part and the rail head by angular movement about an axis adjacent the rail head.

10. An anticreeper, comprising a part provided with an abutment for engagement with the rail base at one side of the rail and with means for giving said part a fixed position in the roadbed in opposition to the tendency of the rail to creep, a shoe arranged to engage said part and the rail base at the' other side of the rail and a rolled bar bent to U shape and arranged tobe forced in between said shoe and the rail head.

11. A device for preventing the creeping of rails, comprising a tie plate provided with means for engaging the rail base at one side of the rail, a part which engages the rail base and said tie plate at the other side of the rail, and a spring constructed to be forced in between the under side of the rail head and said part by rotation of said spring about an axis adjacent the rail head.

12. A rail anchor, comprising a holding plate, a rail base engaging element and a U shaped bar engaging said element and the under side of the rail head and exerting pressure thereon in tending to resume a shape from which it was sprung.

13. A device for preventing the creeping of rails, comprising a tie plate, a shoe engaging said tie plate and the rail base and a bar, bent to form two arms, engaging said shoe and the rail head so as to be rotatable about an axis adjacent'the rail head and exerting pressure thereon in tending to assume a position from which it was sprung.

14. A device for preventing the creeping of rails, including, in combination with the rail and a tie plate a part engaging the rail base and the tie. plate and a two-armed resilient element so engaging said part and the rail head that it may be forced into position by rotation about an axis adjacent the rail head and that longitudinal movement of the rail-in relation to the tie plate and said part will cant said element and automatically increase the grip of the device upon the rail. 1

15. An anticreeping device, including, in combination with the rail and a tie plate, a shoe engaging the rail base and said tie plate at one side of the rail and a spring constructed with two arms so engaging said shoe and the rail head that it may be forced into position by rotation about an axis adjacent the rail head and that movement of the rail in relation to said tie p late will produce angular movement of said spring and automatically increase the hold of the device upon the rail.

16. An anticreeper, comprising a holding plate, a. part constructed to engage the rail base and said holding plate at one side of the rail and a bar so engaging said part and the rail head that it may be forced in between the rail head and said part by angular movement about an axis adjacent the rail head.

17. An anticreeper, comprising rail gripping elements engaging the rail base at opposite sides of the rail, a two-armed vertically disposed part rotatable about an axis adjacent the rail head, engaging one of said elements and the rail head and means operative to give the lower portion of said vertically disposed part a fixed position in opposition to the tendency of the rails to creep.

18. A device for preventing the creeping of rails, comprising two members engaging opposite sides of the rail base and a spring constructed with two arms and arranged to rotatably engage the rail head and one of said members, said members and said spring cooperating to give the lower portion of said spring a fixed position in the roadbed and to press said members against the rail base.
